That would be the neuroglial cell,the "other" type of neural tissue. As we learn more about them, these "insulators" take on a greater and greater importance. They make sure nerve signals go where they need to go. They can repair themselves (which is a mixed blessing since most brain tumors arise from glial cells). They "cushion" the more finicky and delicate neurons. And most intriguing of all, it may be the glial cells, though the manner in which they facilitate nerve conduction velocity and efficiency, that hold the key to memory and intelligence.
Neurons are the stars, but neuroglial cells are the real talent.
